Very accurate cartridge, (I know, I know it's no more accurate than any other round but it really is!) My P229 held up like a champ. I had thousands of rounds through it. My Glock seemed to get beaten up by the round. Now days I just use a 9mm. The Air Marshalls are replacing barrels every 20,000 - 30,000 rounds or so but they shoot frangible which are harder on the barrels.
